ORLA*: Mobile Manipulator-Based Object Rearrangement with Lazy A*

no code implementations24 Sep 2023 Kai Gao, Yan Ding, Shiqi Zhang, Jingjin Yu

Effectively performing object rearrangement is an essential skill for mobile manipulators, e. g., setting up a dinner table or organizing a desk.

Few-shot Class-incremental Pill Recognition

no code implementations24 Apr 2023 Jinghua Zhang, Li Liu, Kai Gao, Dewen Hu

In practice, the expensive cost of data annotation and the continuously increasing categories of new pills make it meaningful to develop a few-shot class-incremental pill recognition system.

Lazy Rearrangement Planning in Confined Spaces

2 code implementations19 Mar 2022 Rui Wang, Kai Gao, Jingjin Yu, Kostas Bekris

Object rearrangement is important for many applications but remains challenging, especially in confined spaces, such as shelves, where objects cannot be accessed from above and they block reachability to each other.

Consistent Representation Learning for Continual Relation Extraction

1 code implementation Findings (ACL) 2022 Kang Zhao, Hua Xu, Jiangong Yang, Kai Gao

Specifically, supervised contrastive learning based on a memory bank is first used to train each new task so that the model can effectively learn the relation representation.
